Question for someone smarter than me. I may have someone who is gonna buy my pearl. How do i make sure pin number is unlocked and esn is clean? Will i have to call att? Do they do it? Does it matter that it was in my dads name when i bought it? Thanks for any help!!!

If the phone is still in your dad's name, it will be easier if he does this. Contact Att, and tell them your planning to take the phone out of the country, and so need it unlocked. They will provide the unlock code for free. As far as cleaning up personal info, doing a complete wipe and then reloading the OS, without a backup of yours installed will solve that. ESN, that's for the opposite type of network, such as VZW.

You had it switched, or cancelled? I'm guessing the device is still on the account. The pin never changes (caveat, there are exceptions, but we won't go into that), try calling them yourself, since the phone was in use by you last.
